' N EWSPAPE R-WRAPPING MACHIN E.

SPECIFICATION forming part of Letters Patent No; 522,198, dated July 3, i894. I

Application filed-October 7, 189a.

- Improvements in Newspaper-Wrapping Machines, fully'described and represented in the following specification and the accompanying drawings, forming a part of the same. 7

The object of the present invention is to provide an improved machine of that class used in Wrapping newspapers and other publications for mailing and generally known as newspaper wrapping machines, and especially to provide a simple and efficient wrapping machine of high capacity.

The present invention relates to a'machine in which the paper and wrapper are rolled together into. cylindrical form by feeding devices co-acting with a core inside the paper and the core withdrawn independently of the feeding devices to deliver the paper.

In the preferred form of the embodiment of my invention, the core is made in two parts, which are withdrawn inopposite directions for the delivery of the wrapped-paper,- and the paper is delivered flat 'by leading off the paper and wrapper by their leading ends with the rear end of the wrapper overlapping upon the first layer of wrapper on the paper, so as to be pasted down and secured by suitable pressing devices,a suitable switch operating between the two parts of the core being used to guide the paper from the core, and the core preferably being so constructed as to allow a wrapper of substantially the width of the paper to be used.

Any suitable feeding devices may be used with the core, but I preferably use a single broad belt extending over both portions of the core, and acting not only as the feeding device co-acting with-the core toroll thepaper, but also to aid in feeding the paper in delivering the latter from the core, so'that a constant pressure is kept upon the paper in its passage from is fully set.

The length of the stantially one-half the periphery of the core, and the wrapper of" sufficient length to exthe core, and until the paste I paper is preferably sub- Serial No. 487,603. (No model.) i

I tend completely about the paper on the core,

and overlap upon the first layer of wrapper on the paper suff ciently for pasting. Withv the paper of this length, the leading ends of the paper and wrapper are taken by the core 5 5 simultaneously, and the paper and wrapper are rolled upon the core during one rotation of the latter, and upon the second rotation are guided from the core 'bythe switch, the part of the wrapper not supported by the pa- 6o per'being carried in so as to lie against the paper, and the rear end of the wrapper overlapping the first layer of wrapper upon the paper is pressed down by the pressing and delivery devices so as to be pasted by paste previously applied, either to the rear end of the wrapper, or to the first layer of wrapper upon the paper, the wrapped paper thus being delivered as a flat product.

In delivering the paper and wrapper from the core I preferably employ a switch which allows the paper and'wrapper to pass with the core in its first rotation, and is shiftedon the second rotation into position to guide the paper and wrapper from the core and into the grasp of the pressing and delivery devices, by which the pasted wrapper is'secnred. The papers may be previously folded to the desired size by folding devices provided in the machine, or the papers may be folded previously, and the wrapping mechanism form an independent machine which may be fed by hand or suitable feeding devices. Thus the wrapping mechanism may be combined with the delivery mechanism of a printing press, or with a folding machine of any of the common forms, wrapperffeeding and pasting mechanisms being added so that the folded paper is automatically wrapped and delivered, or wrapper and paper feeding devices of 0 any suitable form may be combined with the wrapping mechanism to form an independent paper or pamphlet wrapping machine.

In the accompanying drawings forming a. part of this specification, I have shownanin 5 dependent wrapping machine embodying my invention in its preferred form, the paper and wrapper being fed to the wrapping mechanism by feeding rolls, and the pasting mechanism being arranged to apply paste tothe xoo rear end of the wrapper as it passes to the wrapping mechanism, and a full description of this machine will 110w be given in connection with the drawings, and the features forming the invention specifically pointed out in the claims.

In the drawingsz-Figure 1 is a side elevation of the gear side of the machine. Fig. 2 is a central vertical section. Fig. 3 is a horizontal section on the line 3 of Fig. 2. Fig. 4

is a front elevation, that is, looking to the left in Fig. 1. Fig. 5 is a vertical section on the line 5 of Fig. 1,1ooking to the left. Figs. 6 and 7 are partial views on an enlarged scale similar to Fig. 2, but showing the wrapping machine in different positions during the operation of wrapping.

The frame of the machine may be of any suitable form to support the operating parts. As shown, it consists of two side frames A, B, in which all the parts of the machine are supported. it

The core upon which the paper and wrapper are wound consists of two short cylinders C, D, carried byshafts 11, 12, mounted in the opposite end frames A, B and in the upper part of the machine, the cylinders extending within the frame so as to engage the paper at its opposite side edges. The cylinders C, D, are preferably cut away at their inner ends as shown so as to leave only a small portion projecting opposite the paper, these projections forming the parts co-acting with the feeding devices in feeding the paper, this cutting away of the cylinders permitting a wrapper of the same width as the paper to be used, as fully explained hereinafter.

The cylinders G, D, forming the core are inclosed within sleeves G, D, havinghubs 0, cl, splined to the shafts 11, 12, so that the shafts 11, 12 rotate with the sleeves C, D, while at .the same time the cylinders G, D, and shafts 11, 12, are free to move longitudinally in the sleeves so as to project therefrom for seizing the paper during wrapping, and to be withdrawn within the sleeves for the release of the wrapped paper for delivery.

WVith the cylinders O, D, and sleeves O, D, coacts a belt E extending partially about the cylinders from the side on which the paper is 1 received, this belt being of sufficient Width to extend between and over the sleeves G, D.

This belt E isdriven froma roll G, mounted in the frames A, B, above the core, and is led rearward over the latter, and then nndera roll H mounted in the frame, outward from the wrapping mechanism to the rear of the machine, and under a roll I returning thence above. the wrapping mechanism directly to roll G, the length of the belt between the rolls II, I, being sufficient to provide for the holding of the paper in form and with the wrapper under pressure until the paste has set. The roll I forms one of the delivery rolls of the machine, the belt E thus acting as a feeding belt in combination with the core to roll the paper and wrapper and forming also one set of the delivery belts by which the wrapped paper is delivered, the other set consisting of a series of short belts L extending about the second delivery roll or series of belt rolls K and driven from belt rolls M below roll II. The roll G co-acts with a roll 0 mounted in the frame A, B below it to form apair of feed ing rolls by which the leading ends of the pa per and wrapper are received and advanced over guides P to the core. These guides 1 guide the paper from the rolls G, O, to the wrapping mechanism for the first rotation and integral therewith are a second series of guides P" extending rearward and curved concentrically with the core which serve to guide the leading ends of the paper and wrapper back to the belts E on the first rotation of the core. It will be understood, however, that separate guides may be used for these two purposes, if desired.

On the opposite side of the core from the belt E, is mounted a seriesof rolls or disks S which engage the paper during a part of its first rotation, and aid the belt E and core in securing its proper rotation, and these disks extend inside and between a series of guides U which, curved about the line of movement of the paper opposite the belt E, are carried by a rock shaft and at their rear end carry the switch V, the switch being thus mounted so as to swing in a vertical plane.

The guides U act to guide the leading ends of the paper and wrapper while it is out of the rear end of the guides P, so that the paper and wrapper are positively guided thereby, and held gripped by the projection a during the entire rotation of the core, and the wrapper held pressed against the paper.

The switch V is actuated by rock shaft 31 on which the guides U carrying the switch are mounted, so as to throw the switch from the position shown in Fig. (5 in which the paper and wrapper are guided about the core too from the roll II to the disks S and guides I during the first wrapping rotation of the core, to the position shown in Fig. 7 in which the leading ends of the paper and wrapper are guided. off to the delivery belts during the second or delivery rotation of the core.

The switch V consists preferably of a series of fingers forming guides for the paper and wrapper, and a second series of guiding fingers T extending rearward-from and betweenthe fingers forming the switch V are preferably used, so as to securea complete continuous guide when the switch is in the position shown in Fig. 7', andlying within the circumference of, but extending rearward of the belt rolls M so that this guiding may be continued until the paper is securely grasped between the belts E and L. It will be understood, however, that a continuous plate may be used in place ofthe fingers forming the switch V, and that other suitable means may be used for securing the proper guiding of the paper in delivery. The construction shown, however, is simple and efficient, and will be foundwell adapted for the purpose.

The paste may be applied to the rear end of the Wrapper prior to the wrapping opera tion, or in the machine at any suitable time.

In the construction shown, the paste is applied to the rear end of the wrapper before the lat ter reaches the wrapping mechanism, and for this purpose a paste fountain W and fountain roll X are provided, by which paste is supplied to a rotating paster Y mounted in position and arranged to apply paste to the wrapper against a roll Q,which roll co-acts also with a series of guidesRto aid in advancing the paper to the rolls G and O, as shown in Fig. 7. The paster Y is constructed to apply paste only to the portions of the wrapper between the guides P, so that the pasted portion of thewrapper will pass forward out of engagement therewith, but will be brought into contact with the wrapper as the leading ends of the paper and wrapper pass 'the guides P on the second rotation of the core.

The operating parts of the machine are driven from the main driving shaft'Zbythe following connections:-The hubs c, d of the sleeves C, D, are provided with gears 13, 14:,

which engage respectively gears 15,16 carried by the shaftof roll G, and thecore is thus driven. The roll G carries, also, at one end outside the gear l5 a gear 17 which engages a gear 18 on the shaft of roll 0, and the roll 0 is driven from the main driving shaft Z by gear 19 on the main driving shaft engaging gear 18. As will be seen, the gears are so timed that the cylinders O, D, and sleeves O, D are rotatedtwice to each rotation of the main driving shaft Z, and the belt E driven by roll Gr moves at the same rate of speed as the cylinders O, D. The belt rolls M and belts L are driven from the main driving shaft Z by gear 19, intermediate 20 and gear 21 on the shaft of roll M, and this shaft in turn drives theshafts of rolls S by gears 22, 23 at the oppositeside of the machine from the gears 20, 21. A uniformspeed is thus secured for all the parts co-acting with thepaper in advancing and deliveringthe paper. The shaft of roll 0 carries outsidegear 18 a small gear 21 which engages a larger gear 25 on the shaft of roll Q, so that the surface speed of the roll Q is the same as that of the roll G, and the pastor Y is driven by'a small gear 26 on the shaft of roll Q engaging a gear 27 on theshaft of the pastor, and gear'27 cams F provided, with cam grooves fin which" in turn drives the fountain roll X through gear 28. e I,

e The cylinders C, D are moved longitudinally by the following means: The Qmain driving shaft Z carries at its opposite ends run bowls carried by levers 29 pivoted on the frame, and at their opposite ends provided with bowls running in grooved collars 30 carried by shafts 11, 12, so that as the cams F rotate with the driving shaft Z, the cylinders O, D, are advanced and retracted in proper time for the receipt and delivery of the paper. The switch V is carried by the rock shaft 31 mounted in the side frames A, B, and carrying inside the frame B a crank arm 32 connected by a'pitman 33- with abell crank lever 31 pivoted on the frame B, the other arm of which lever carries a bowl which rides in a cam groove in a disk 35 carried by the main driving shaft Z inside the frame, so that the switch is thusmoved positively bythe cam in both directions.

The operation of the machine will be understood from a brief general description in connection with the drawings and the detailed description of the parts above given.

As shown in themainviews the paper ac and wrapper yhave been received by the belt roll G and feeding roll '0, and advanced thereby over the guides P to the core, and the paper and wrapper have been gripped between the paper and wrapper are woundabout the core,

passing inside the switchfand being guided during this rotation by the switch and guides U, P, and at the end of the first rotation the parts are in the position shown in Fig.6, the pastor, as ,shown, having just applied paste to the flap of the wrapper, although it will be'understood that the time of applying paste will depend upon the length of the wrapper used, which may be varied to some extent. Upon the second rotation of v the core, the leading end of the paper and wrapper is carried about in the same path as upon the first rotation until it reaches the rollH, but as the second rotation of the core continues, and the leading end of the paper approaches the'switch V, the switch is shifted bythe connections previously described and thrown inward into the position shown inFig. 7, so that it operates to guide the leading end of the paper and wrapper fromthe core out be tween the roll Hand guides T, soas to be gripped between the rolls II,M and belts E, L, and thus carried rearward and delivered. Asthe leading end of the paper and wrapper is thusled from the core, the loose portion of the wrapper is carried inward onto the inner surface of the paper, as shown in dotted lines in Fig. 7; the special form of the core cut away at its ends to the projection a permitting the switch to throw thewrapperin with,- out tearing the edges and the wrapper to be drawn 0d the core during the withdrawal of the two parts 0, D, which is com mencedsim ultaneously with the movement of the switch V, and as the flap of the wrapper passes to thefcore, the cylinders C, D, are fully with drawn, and the wrapper left free, although of the same width as the paper. As the paper and wrapper are advanced between the delivery belts E, L, the rear end of the wrapper is pasted down upon the layer of wrapper upon the paper and the paper delivered in flat form between the rolls I, K, the pasted portion of the wrapper being pressed down a sufficient length of time by the delivery belts and rolls, so that the wrapper is firmly secured upon the paper.

In the preferred construction shown, the length of the paper is substantially one-half the periphery of the core, so that the portion of the wrapper not supported by the paper is substantially the length of the paper, and is simply carried inward against the paper in delivery. \Vhile this construction is preferred, however, it will be understood that a longer paper may be wrapped, the withdrawal of the core permitting the paper also to be doubled in against itself, as it is led ed the switch V, the special form of the core permitting the paper to be thus led off while the core is being withdrawn, or alonger paper may be wrapped without employing the core of special form, provided the grip of the delivery devices be loose enough to allow the wrapper to slip as the paper is straightened out, so as to draw up the rear end of the wrapper sufficiently to aiford the wrapper to extend about the flattened paper. It will be found preferable, however, to use a paper of a length substantially half the circumference of the core, as shown, and the machine shown is especially adapted for such use. The core need not be cut away at the edges as shown, if the wrapper is of a width less than the distance between the two parts of the core, or even with a wrapper somewhat wider than this distance, if the parts of the core are withdrawn at such a time as to enable the loose parts of the wrapper to be carried inward by the point of the switch as the paper is led off, but the construction shown will be found more efficient.

It will be understood that many modifications may be made in the construction shown by those skilled in the art withoutideparting from the invention.

WVhile the invention has been described as applied to wrapping newspapers and other publications, it will be understood that the machine may be applied to wrapping other articles which can be rolled into cylindrical form, and that such uses are within the invention, and the term paper is used in the claims to include such other articles.

I do not claim herein the combination with a core, of feeding devices or belts co-acting therewith to advance a paper and wrapper and wind them upon the core by pressure between the feeding devices and core, and means for delivering the Wrapped paper from the core, or such a construction in which the paper is delivered by withdrawing the core, as these subjects-matter are included in my Patent No. 508,567, dated November 14:, 1893 I do not claim herein the method of wrapping newspapers and other publications,
